摘要
目的研究血浆N末端BNP前体(NT-BNP)对老年人不典型心力衰竭病人心功能的诊断价值,并与心脏超声检查结果进行比较。方法对60例老年病人测定血浆NT-BNP浓度,并行超声心动图(UCG)检查,应用统计学方法分析各项指标之间的关系。结果慢性心力衰竭(CHF)组与非CHF组NT-BNP水平比较差异有显著性(t=13.19,P<0.001);以NT-BNP>450 ng/L为界值,NT-BNP诊断不典型心力衰竭灵敏度高于左室射血分数(u=4.22,P<0.01)。结论NT-BNP是CHF诊断和鉴别诊断有效的量化指标,且快速准确;与UCG相比,NT-BNP对老年人不典型心力衰竭的诊断灵敏度高,对CHF具有排除诊断优势。
Objective To find out the clinical value of serum level of nitrogen terminal brain natriuretic peptide (NT- BNP) in the diagnosis of old non-typical heart failure patients and its advantages compared with the ultrasonic cardiograph (UCG). Methods Sixty patients received both NT-BNP test and echocardiography examination. A statistical analysis was used to analyze the relationship between these items. Results The serum levels of NT-BNP were significantly different between chronic heart failure (CHF) group and non-CHF group (t= 13.19,P〈0. 001). NT-BNP had higher sensitivity than left ventricle ejection fraction (LVEF) when NT-BNP〉450 ng/L (u=4.22,P〈0.01). Conclusion NT-BNP is a quantitative index in the diagnosis and differential diagnosis of CHF. Compared with UCG, NTBNP showed higher sensitivity and negative predictive value in the diagnosis of CHF.
